Application filed March 21,

' warps for installation in the loom.

While the invention may be embodied in widely different forms and certain of its features may be usefully employed in connection with warp replenishing machines other than those of the drawing-in type, herein, for illustrative purposes, we have shown one embodiment thereof in the form of a transfer apparatus for use in conjunction with warp drawing-in machines, such apparatus being adapted to load or unload the machine with the warp, harnesses or other loom elements employed, and being of such a nature as to increase the capacity and output of such machines, and facilitate the work of drawing in the warps thereon.

Our invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims. Y

Referring to the drawings:

Fig. 13 is a side elevation of the modification shown in Fig. 12; and

Fig. l lshows still another modified form of harness holder.

Referring to the drawings and to the embodiment of the invention by which we have therein illustrated the same, we have shown one form of transfer, or loading or unloading, device cooperatively associated, by way of example, with a well known type of drawing-in machine 1, the latter being of the same general construction as that shown in Patents 755,861 to Field, 871,680 to Field at al., and 862,474 to Hathaway.

Such machine is herein shown, for-the sakeof illustration, it being obvious that the transfer device described'may, with suit- .able modification, be usefully employed both with warp drawing and other machines of widely different construction.

the weaving elements, that is to say, the

warp threads and those elements, such as the harnesses, reed and drop wires, which accompany and are associated with the drawn-in warp for the control thereof in the loom, are supported in a generally parallel arrangement lengthwise the machine, wliile an appropriate needle 2 (see Fig. 5) or other thread placing device, carried by the traveling carriage 3 is caused to traverse the extent of the reed and harnesses and place successive warp threads through the desired heddle eyes and the selected reed dents, these being appropriately positioned for that purpose in the needle path by suitable selecting and positioning mechanisms.

In this, or'in any other type of drawing-in machine, much time is usually expended in installing the loom elements in the machine preparatory to the drawing-in operation,

and much time is apt to be expended in disconnecting and removing the drawn-in Warp and other weaving elements from the machine after the drawing-in operation, as

well as in checking up errors in the placing of the threads and correcting such errors when they are found to have occurred. In the described form of machine selecting and positioning devices are employed for the harnesses which must be carefully applied to the harnesses when the latter are installed in the machine, and carefully removed therefrom when the harnesses are withdrawn.

To reduce the period of idleness or inaction thus forced upon the machine, we have provided (as shown in Fig. 1) for use cooperatively with the drawing-in machine, a movable transfer device 4 which is adapted to present the loom elements for installation in the drawing-in machine in susbtantially the same general relation they are to machine.

- the occupy therein, so that they may be conveyed to the machine, installed therein, and thereafter withdrawn from the machine after the drawing-in operation has been completed. Through the provision of two or more of such transfer devices it is possible during the drawing in of one Warp to correct and check simultaneously the previously drawn-in warp while the latter is sustained upon one of these handling and conveyin devices and to make such other preparatlons for the installation of the warp harness or reed in the loom as are now made while those elements remain supported in the drawing-in machine. At the same time a Warp may be made ready for installation in the machine as soon as the warp then in machine is drawn in, this being accomplished by arranging the loom elements upon another loading device in the relation they are to occupy in the machine and applying to the harnesses those portions of the separating and positioning mechanisms which are detachable from the drawing in In this manner the drawing-in machine can be kept in substantially conceiving pockets 15. The

tinuous operation without those prolonged interruptions which have heretofore been necessary in installing the undrawn warp in the machine and taking the drawn-in warp therefrom.

Referring to the particular type of warp handling device illustrated, the same comprises a frame work consisting of end frame members 5 and (3, suitably united by longitudinal tie rods 7 and so mounted as to be readily conveyed from one point to another, as upon the roller casters 8 of any suitable construction.

Referring first to the means for supporting and handling the warp beam, near the lower part of the holder there is provided means for sustaining a warp beam. Such beam sustaining means may be provided in members 5 has a concave pocket 9 in its upper end whichpocket is one end of the pintle or shaft 10 for the warp beam 11. The opposite end of the warp beam shaft rests in a similar pocket formed in an intermediate frame member 12 (Figs. 2 and 4) the latter being adjustable lengthwise the tie rods 7 so as to ac commodate different lengths of warps and warp beams.

The warp beam when placed in the loading device preparatory to installation in the machine will occupy the position shown in Fig. 1, the ends of the Warp threads being secured by the clamp 13 fastened to the edge of the beam.

When it is desired to install the warp (together with the other Weaving elements) in the machine the loading device is pushed along the floor of the mill of the drawing-in machine, as indicated in Fig. 1. stationary beam-holding means are provided at the machine, the same herein comprising the supports 14 having the beam resupports are so positioned as to project out from the base of the machine to be-closely adjacent and in registration with the pockets members 5 and 12 when the is finally positioned at the machine.

Y The supports 14 rest upon the channel iron 16 and the T-iron members 17 and 18 (see Fig. 2 in dotted lines) both occupying loading device a fixed position relatively to the drawing-in are adjustable and 17, while seadjustable attachproviding a shoulto the front side To receive the warp beam suitableadapted to receive 9 on the frame i dered part 19 on each support underlying the upper lip of the channel iron 16; The T-irons 17 and 18 also provide a positioning means for the loadin mechanism, the frame members 5 and 6 belng provided with projections 20 and 21, res ectively, which are pushed up against the l'-iron when the sition of loading device is positioned, thereby insuring repeatedly thesame and the correct pothe various partsgof the loading device in a transverse relation to the drawing-in machine. loading device longitudinally the drawingin machine is insured by the contact of the projection 20 on the frame member 5 with the upri ht part of-an angle iron 22 (see Figs. 2 and 5) located at one end of the T- iron 18.

When the loading device has'been pushed into the proper position as described, the frame members 5 and 12 are brought into registration with the su ports 14 and the warp beam can then be displaced from the pockets 9 on on the stationary machine supports. This may be accomplished by any suitable means, I

but herein there are provided a pair of lifting devices 23, eachin the form of a U- shaped bracket, which areadapted to be elevated by the foot treadle 24 under the ends of the warp beam shaft, so that the latter is lifted out of the pockets 9. The

warp beam can then be manually rolled along the brackets over the stationary pockets 15 and dro ed therein by releasing the foot tre'adle. ia c'h bracket is carried by a verticalplunger rod 25 adapted to be raised or lowered by rocker. arms 26, the rocker arms being connected each to the squared shaft 27, the latter having the foot treadle 24 directly connected thereto. The plunger rods 25 are guided in bearings 28 attached to the frame members 5 and 12, so that the bracket nextadjacent the frame member 12 is adjustable with the latter lengthwise the holder.

Referring now to devices for supporting.

the harnesses, reed and other loom elements to be installed, the loading device is provided with upright supports herein in the 7 form of rods 29,- held one in each frame member 5 and 6, such supports carrying each one or more supporting arms on which the various loom elements can be arranged in substantially the relation they are to occupy or have occupied in the drawing-in machine. In the embodiment of the invention shown in Figs. 1 'and 5, inclusive, there are provided at each end of the apparatus upper and lower supporting arms 30 and 31 respectively. E'a'ch arm 30 is mounted for horizontal transverse sliding adjustment in a holder 32, there being provided a set screw 33 to fix the adjusted position of the arm. The holder 32 in turn is mounted for longitudinal adjustment along the supporting rod 34, the latter preferably havi g a square or other noncircular cross section. The rod 34 in turn is sustained at each end bya bracket or hanger 35 secured to the upright- 29 such as to permit vertical adjustsupport by the adjusting screw 36.

ment as The correct position of the the loader into the pockets15 withdrawal from the machine. .lower supporting arms 31 are mounted in holding pockets.

Each sup iprting arm is preferably grooved (see ig. 14) or otherwise provided with positioning means for the harness shafts so that harnesses, to the required number, may be hung upon the supporting arms in the required relation, and, if desired, po-

sitioning devices may also be employed for the supporting bars of one or more sets of drop wires, as indicated in Fig. 3. It will be seen that the harness supporting arms have all required adjustments for variations in the height and spread and the number of holders 37 carried by the transverse rod 38, the latter sustained by the hangers 39, these several parts being adjustable in substantially the same fashion as the supporting parts for the arms 3Q.

The lower supporting arm 31 (as shown in Fig. 3) may also be grooved at 40, or

otherwise fashioned to provide a support for the reed 41 when the latter is withdrawn from the machine with the drawn-in warp. The loader may be arranged'to hold the reed in the desired relation with reference to the harnesses when the latter are applied to the machine for installation therein, or the reed may be manually and separately installed in the machine irrespective of the loading device, it being ordinarily a' simple and quick matter to apply the reed to the reed holder ofthe machine.

In' making use of the described loading mechanism when it is desired to equip the same with loom elements for installation in the machine,-the warp beam with the undrawn warp thereon is placed in the warp The harnesses are then hung upon the supporting arms 30 and 31 in the positions represented in Figs. 1 and 3- and the harness separating devices, if the .machine, and require adjustment to the harnesses prior to the drawing-in operation, are then applied to the several harnesses.

In the described form of machine (see Figs. 6 and 9) the heddles are separated by the coils of a helical spring 42, (as described in the aforesaid Patent #775,861). It is customary to apply these each as a permanent attachment to its harness, a cord 43 (see dotted line, Fig. 9) being drawn through the coil to keep the heddles in place in the s ring when the harness is in the loom. hen the harness is used in the loom (see patent to Lanning, #795,989) a rod 44 is inserted through the spring 42 and holds the spread of the harnesses.

' consisting in the substitution rator worm shaft for the cord 43, has here- 1 the latter near the underside of the upper harness shaft by means of the cord 43, out

I of line of the warp threads in the shedding 'turned, the worm will act to separate and 1 position the heddles and the heddle eyes (see igs. 6 and 9).

The application of the detachable separating devices in the case of of the sepatofore. been performed after the harnesses have been placed in the drawing-in machine. This operation, however, can be performed withequally or greater facility after the harnesses have been hung in position on the loading mechanism as described, and prior to their installation in the machine, thereby materially reducing the period of time durv ing which the machine is idle.

The same 1s true of the operation of raising the separator spring and fastenin it in the position shown in'dotted lines ig. 9)

after the drawing-in operation. This, as well as the checking and correcting operation also can be performed with equal or greater facility on the unloading device than in the machine.

lVith the loom elements installedv in the loading machine and the harness separating devices applied thereto, the loading device may be then moved from the preparatory operation has been carried on to the drawing-in machine and positioned as represented in Fig. 1. The warp beam is then transferred to the fixed supports 14, as previously described. The harnesses which have been brought into substantially the position they are designed to occupy in the drawing-in machine can then be secured thereto by attaching to the upper harness shafts the harness supporting members 47. In the described form of machine these comprise hook supports having each a spring or other connection 48 and depending each from a rod 49 resting upon suitable roller supports 50 carried by the machine frame. The upper harness shaft of each harness having been attached to its spring supported hook and the lower harness shaft to a suitable stretching device such as the depending weight 51 and the reed 41 having been presented to its holder either by the loading mechanism or independently thereof, the entire loading frame can be moved back out of the way and entirely free from the machine.

If drop barsare em loyed, they can be suspended upon suitabl za hanger bars resteach harness,

. the lower arms the position where ing on the supporting and placed in their respective supports in the drawing-in" machine.

After withdrawal of the machine, the warp can be applied to the warp clamps in-7 the usual manner, assuming the position represented by dotted lines in Fig. 1.

After'the drawing-in operation has been performed an empty'loading frame can be pushed up into the position shown in Fig. 7 1. The Warp beam can then be transferred from the fixed supports 14 to the beam holding pockets on the holder by pressing down upon the foot'treadle 24 and the harnesses and drop bars can be transferred to the 84 leader by merely detaching them from their supports on the warp drawing machine. The ends of the drawn-in threads are knotted together outside the reed so as to prevent escape therefrom, and the latter is 85 placed in the holding pockets provided on .31 as represented in Fig. 3. With the parts in this position the transfer frame can then be withdrawn from the machine and the drawn-in warp and loom elements, appearing as'shown in Fig, '3, can be conveyed to that part of the room or mill where the checking and correcting operation is to be carried on and where the'harnesses are to be prepared for the loom. The installation of a new warp to be'drawn in, as first described, can follow immediately the withdrawal of the drawn-in warp, so that the interval between successive drawing-in operations on the machine is reduced to a minimum.

If desired, the transfer device may be provided with means for holding a warp thread clamp, such as the clamp 52, which clamps the'warp when in the machine between the Such holding means are herein provided in the form of slightly inclined brackets or hangers 71' adj ustably secured one over each 1 end of "the warp beam on the square sec- 11( tioned supporting rod 38. Each hanger is provided with the hinged latch 72 which can be thrown down to hold the clamp in the hanger as seen in Fig. 3; When the transfer device is moved into position for the withdrawal of the drawn-in warp from the drawing-in machine the latch 72 is thrown back out of the way and each hanger assumes a position under the end of the clamp 52 seen in Fig. 1. After the warp beam has 'been transferred to the transfer device, the

pivoted latchesare thrown down, thereby securing the clamp to theunloading mechaas a convenient holder therefor, or

one-half the clamp, thatis to say, one of the two members composing the clampjmay be left in the drawing-in machine while the other clampmember is carried in the bracket on the transfer device so as to be brought into proximity to its intended position on the drawing-in machine whenthe loading device' is properly positioned at theside of the machine. 7 T

Having reference to the harness eye separating devices, upon the described form of machine (see Figs. 5 to 9, inclusive) each separator shaft is disengageably connected to a suitable drivin device upon the machine, such device herein consisting of a socket member 53 in which the end of-the shaft is held by the hinged'sprin -pre'ssed key member 54. The socket mem er 53 is driven from a drivingshaft 55, the latter having a rotatably adjustable connection therewith by means of the crank member 56 and pin 57, which latter can be forced into engagement with any one of a number of holes 58 formed'in the inner face of the socket head. The driving shaft 55' is operated at intervals by means of a pattern mechanism (not herein shown) so that separator shafts are intermittently turned in predetermined order ness eye from a selected one ofthe five sets of harnesses employed. The pitch of the separator worm is coarse .and the arrangement is such tion and distance that one-half a revolution of the separator shaft moves the harness e e from the position a (see Fig. 9) path into the position b (within the needle path) and a second half revolution of the separator shaft moves the said eye into the position 0 (again out of the Iieedle path). 1

It will be seen that in the case of the described harness eye separating devices, in addition to the carefulapplication of the separator shaft to the'harness and the harness separating spring which must be performed before a drawing-in operation can 'be carried out, the separator worm must also be carefull adjusted with reference to the driving sha 55' both as to angular posilengthwise the separator shaft therefor, for upon such angular and longitudinal adjustment dependsthe exact position at any given time of the particular -harness eye or eyes controlled thereby..

Heretofore, w ere the harnesses and other elements have been se arately installed and prepared in the drawlng-in machine itself, but one set of separator shafts hasbeen required and it has been necessary to adjust each shaft with its wormonly at the outset. Where a loading device of the type described is employed and the harnesses are arranged and prepared prior to installation in the drawing-in machine, in order to avoid the necessity for a se arate adjustment of each separator shaft a ter it has been placed upper so as to present a'har.-,

' harness sha out of t e- -in the machine, thereby considerabl delay 1 ing the drawing-1n operation, it is esirable to employtwo or more sets of separator shafts, the shafts and worms ofthe several sets being interchangeable for any one harness. Our invention, therefore, contemplates the employment, in conjunction with a drawing-in machine and two, or more transfer devices, also two or more sets of detachable'interchangeable harness positioning devlces.

'In Fig. 10, we have shown a modified form of supporting device for the heddles, whereby the lower supporting arm, if de-.

sired, may be, dispensed with. Herein the supporting arm 59 is pivoted at 60.upon the upright support 61. The arm 59 may be turned up out of the way about the pivot, but when turned down in the horizontal position, it is there "held by the stop pin 62. Carried by the arm is a series of blocks 63, adjacent ones being separated by the spring .64, but adapted to be forced together by the pivoted cam member having the handle 66. The several brackets have each a rubber facing. 67. The harnessesmay be placed in position upon this support by insertin the harness shaft between adj acent-b ocks and between the rubber facings 67 after which the cam member 65 can be turned to compress the blocks and hold the harnesses fast between the same. This sup ort engages the sides of the its between the ends thereof and cannot therefore interfere with the spring 42 when the latter is held in the raised P081- tion shown in dotted lines in Fig. 9. The end block in the series ma be provided with depending clips 68 whic may be suitably formed to receive the reed'41. It will be understood that the holder shown in Fig. 10 is duplicated at each end of the latter so that the loom elements can be applied to the machine and withdrawn therefrom as previously described in connection with the loadingvmechanism in Fig.1.

, hile the construction shown in Fig. 10 contemplates ase'ries of common p members for the several harnesses, indiifi? we have shown a third in place of the upper end of the loadthere is provided an angle iron The gripping devices, such as are shown in Fig. 10, are especially convenient for unloading the loom elements from the drawmg-m machine, and, if desired, some such expedient may be employed for unloading, while the sword shaped or other supporting arms 70 are employed in loading the 'machine, or the gripping devices or supporting arms alone, as the case may be, may be emplo ed in both loading or unloading.

ur invention is capable of use with suitable modification either as an unloading device exclusively or a loading device exclusively, although the same is herein described as erforming both functions.

hile we have herein shown and described for purposes of illustration one specific form of the invention, it is to be understood that extensive deviations may be made from the details of construction as well as the arrangement of parts and application made of the invention without departing from the spirit thereof.
